Product Description:
The MHD115C-024-NG1-RN is a servo motor manufactured by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It serves as a rotary actuator in industrial automation where precise speed regulation and repeatable positioning are required for tasks such as tool drives, gantry axes, and conveying stations. The motor’s C-length frame and integrated holding brake support secure load retention during power interruptions, while the liquid-cooled housing allows high torque in confined machine spaces.
During continuous duty, the motor sustains 70.0 Nm of standstill torque, so static loads can be held without thermal overload. A rigid 192 mm square flange aligns with common mounting patterns, and the 180 mm centering diameter helps keep the rotor concentric with attached mechanics. The enclosure has IP65 protection, which prevents dust ingress and resists low-pressure water jets during washdown or coolant splash. Heat is removed through liquid cooling, and coolant passages in the stator jacket help maintain winding temperature across the rated ambient range of 0 to 40 °C. Mechanical installation is simplified because the power connector is oriented to the right side of the housing, matching panel layouts that route supply leads from floor-mounted drives.
Rotor position is monitored by a digital servo feedback (HSF) encoder, and the optical measuring system provides a system accuracy of ± 0.5 angular minutes. The motor uses a plain shaft, which minimizes torsional windup and permits direct coupling to gearboxes or pulleys. Storage and transport are allowed between -20 to +80 °C, so spare units can remain in non-climate-controlled warehouses without degradation. Class F insulation supports thermal durability, and the integrated holding brake locks the shaft when control power is absent.
